This project will evaluate the neurotoxic effects of oxaliplatin. Oxaliplatin is considered the most neurotoxic chemotherapy, and at the origin of peripheral neuropathies. These neuropathies remain a problem in oncology because currently no prevention strategy has proved effective and only duloxetine seems to have a therapeutic benefit in improving symptoms. In the case of oxaliplatin, neuropathy forced oncologists to reduce the dose or to stop the chemotherapy, potentially degrading the oncological prognosis.
